Ammonia is NH3. The molar mass of NH3 is 17.0307g.
(1.2*10^3)/17.0307=70.46 moles of NH3.
If you are using significant figures, it is 70. moles of NH3.
Answer:
Arrow.
Explanation:
Hello!
In this case, since chemical reactions are characterized by the presence of some species at the left on an arrow representing the reactants and at the right the products, we understand that the arrow, separating reactants and products is understood as "produces" or in very chemical words "yields"; therefore, the symbol that takes the place of the word yields is an arrow.
Best regards!
Answer:
The answer is below
Explanation:
The density of an object is its mass per unit of volume. Dense objects feel very heavy for their size, while for objects with low density they are very light for their size.
Density is the ratio of mass to volume; it is given by:
Density (D) = mass (m) / volume (V)
An object sinks in water if the density of the object is greater than the density of water. While an objects floats on water if the density of the object is les than the density of water
